4.4 LED Indications

KEY:
G = green G - Y - R = flashing sequencially
Y = yellow G / Y
R = red G / Y - R = G and Y flashing together,
alternating with R flash

4.4.1. Power-up

Normal power-up: Status LED flashes G, then SOC LEDS
flash G - Y - R, sequentially, then SOC LEDs will indicate
battery charge status with one or two lit battery status LEDs.
Failed bootload: Status LED flashes G, then SOC LEDS
flash G - Y and stop on solid Y.

4.4.2 Status LED

The Status LED indicates charging status and any exist-
ing solar input error conditions. The Status LED is on when
charging during the day and off at night. The Status LED will
flash red whenever an error condition(s) exists. Table 4.4 lists
the Status LED indications.

2) R charging status LED ON with heartbeat blink OFF
every 5 secs is a critical fault that generally requires service.
